Refactor widget tests for H5 line generation and validation
- Simplified tests for H5 line creation, focusing on single line generation with a numeric 16-digit label. - Updated assertions to validate the generated H5 line's label and URI structure. - Removed redundant tests related to default H5 line URLs and local access, consolidating functionality into fewer tests. - Added new tests to ensure correct URL generation from configured fallback order and query parameter handling. - Enhanced test coverage for restoring cached H5 line URLs and validating their structure.

Flutter WebView 套壳 App，启动后会请求 `/client_config/query` 获取 H5 线路配置，并加载第一条可用线路。
|
||||
Flutter WebView 套壳 App。启动时只会生成并加载一个 H5 URL；如果当前 URL 探测或加载失败，壳层会重新生成下一个 URL 并替换当前 WebView，项目运行过程中始终只持有一个 H5 URL。
|
||||
|
||||
默认情况下，非本地 Web 访问会使用当前服务地址的 origin 作为 H5 线路和接口域名，例如访问 `https://app.example.com/app/` 时会请求 `https://app.example.com/client_config/query`。本地访问（如 `localhost`、`127.0.0.1`）继续使用固定兜底域名 `https://h5-test.imharry.work/`。
|
||||
默认 URL 来自代码中的泛域名模板，会生成 16 位数字子域名，并通过查询参数把 Flutter 壳请求地址传给 H5：
|
||||
|
||||
## H5 线路切换
|
||||
|
||||
线路切换在 Flutter 套壳层完成。远程配置不可用时，会先使用启动兜底线路；也可以在打包时覆盖启动线路或配置接口地址：
|
||||
|
||||
```bash
|
||||
flutter build apk --release --dart-define=H5_LINE_URLS=https://h5-one.example/,https://h5-two.example/
|
||||
flutter build apk --release --dart-define=CLIENT_CONFIG_QUERY_URL=https://api.example.com/client_config/query
